Question

what is one benefit of mapping the human genome?
locating the chromosomal abnormalities that cause disease
having the genomes of every living individual on file
choosing the gender or intellectual ability of an unborn child
cloning the individuals that comprise a nearly extinct tribe

Explanation:

Human genome - mapping helps in identifying chromosomal abnormalities related to diseases by studying the DNA sequence. This allows for early - detection and understanding of genetic disorders. The other options are not benefits of human genome mapping. Cloning nearly extinct tribes is unethical and not a goal of genome mapping. Choosing gender or intellectual ability of an unborn child is controversial and not a positive outcome of genome mapping. Having genomes of every living individual on file is not a practical or ethical benefit of genome mapping.

Answer:

locating the chromosomal abnormalities that cause disease
